摘要： An apparatus for providing oxygen-enriched air at a first pressure and at a second pressure, the second pressure being greater than the first pressure. The apparatus comprises, in combination, a pressure swing adsorption system and a pressure intensifier. The pressure swing adsorption system for enriching the oxygen content of air has a pressure of at least the first pressure. The pressure swing adsorption system is adapted to provide oxygen-enriched air to a first outlet at the first pressure and to provide oxygen-enriched air to a pressure intensifier at the first pressure. The pressure intensifier pressurizes the oxygen-enriched air and provides the oxygen-enriched air to a second outlet at the second pressure.

摘要： A method and system for supplying a person with breathable fluid in an irrespirable atmosphere. A package which is attached to a person holds a container having a valve which is activated upon removal of a protective cover. The valve allows a breathable fluid to flow at a variable rate to a supply conduit. The supply conduit is connected to a reservoir. An inhalation check valve connects the supply conduit to the person. Upon inhalation, the check valve will open and allow breathable fluid to flow from the supply conduit. Upon exhalation, the inhalation check valve closes and an exhalation check valve opens to permit the breathed air to flow through a filter where carbon dioxide is removed before returning to be mixed with breathable fluid in the supply conduit.

摘要： A control system for sequentially communicating a source of pressurized fluid mixture to first and second beds of adsorption material to separate at least one component from the fluid mixture and produce a product fluid. A pressure transducer connected to a supply conduit develops a switching signal corresponding to a predetermined fluid pressure in the fluid mixture communicated to the first and second beds of adsorption material. An electronic controller responds to the switching signal to sequentially develop first and second electrical signals. The electronic controller allows the first and second electrical signals to overlap for a predetermined controlled time period. Valve mechanisms sequentially respond to the first and second electrical signal to prevent communication of the fluid mixture to one of the first and second chambers while allowing communication to the second chamber. A first branch of an outlet conduit connects the first bed of adsorpton material to a storage chamber while a second branch of the outlet conduit connects the second bed of adsorption material to the storage chamber. An equalizer valve located in an intermediate conduit between the first and second branches of the outlet conduit, reacts to first and second overlap of the electrical signals to allow the fluid pressure in the first and second beds of adsorption material to equalize when the communication of fluid mixture to the first and second beds of adsorption material is interrupted to complete a cycle of operation.

摘要： In an aircraft breathing system a sensor assembly for monitoring the concentration of oxygen in a source of breathable fluid supplied to a recipient. The sensor assembly has a housing with a chamber therein connected by a conduit to the source of breathable fluid. A restricted orifice member in the conduit allows a sample of the breathable fluid to continually flow into the chamber while an exit port in the housing allows the sample of breathable fluid to flow to the surrounding environment. A sensor responsive to the partial pressure of oxygen is connected to the chamber. The sensor in response to the partial pressure of the oxygen produces an operational signal. The operational signal activates an indicator to provide the recipient with a reading of the concentration of oxygen in the breathable fluid. An aneroid fixed to the housing has a face that engages a seat surrounding the exit port. Whenever the aircraft is above a predetermined altitude to establish a constant absolute pressure for the sample in the chamber. This constant absolute pressure stabilizes the operation of the sensor and thereby maintains a uniform indication of the percentage of oxygen in the breathable fluid above the predetermined altitude.

摘要： A portable breathing apparatus for use in a noxious atmosphere includes a helmet that is closed except for a bottom opening that is provided with a neck seal to permit the helmet to be slipped over the head of the wearer while sealing the open bottom of the helmet to provide an airtight enclosure about the wearer's head. A backpack includes a high pressure oxygen cylinder, that is connected to a regulator valve through a pressure reducer; and a carbon dioxide scrubber, that receives expiration gas from the helmet through an exhaust breathing line which connects to a flexible reservoir which collects the majority of expired gases and which is provided with a relief valve to protect the bag and limit expiration resistance. The outlet of the reservoir is connected to the inlet of the scrubber and the outlet of the scrubber being connected to a second inlet in the regulator valve by a line that includes a heat exchanger associated with the oxygen cylinder so that the oxygen cylinder removes heat from the recirculating gas from the carbon dioxide scrubber. The regulator valve has an outlet chamber connected to the helmet interior through an inlet breathing line and the regulator valve includes an on-off-type valve that delivers oxygen from the oxygen supply to the chamber through an injection nozzle only when inhalation by the wearer causes a pressure drop in the chamber that acts on a diaphragm to open the valve. The gas from the scrubber enters the chamber in a reduced pressure zone adjacent the nozzle outlet, the reduced pressure helping to pull scrubbed gases from the carbon dioxide scrubber.
